Ferritic–Martensitic Structures and Their Effect on HAZ Notch Toughness

Pages 395-398 | Published online: 18 Jul 2013
 

Abstract

The presence of a ferrite-martensite mixed microstructure in the HAZ ofa grade 65 line pipe steel, has been identified. The embrittling effect of this structure on the notch toughness of the HAZ is discussed.

Résumé

La présence d'une microstructure composée d'un mélange ferrite-martensite dans la zone affectee par la chaleur d'un acier it pipeline grade 65, a été identifiée. L'effet de fragilisation de cette structure sur la sensibilité à l'entraille de la zone affectée est examiné.
